The position effect variegation of bw caused by In(2R)bwVDe2 is consistently suppressed by T(2;3)SbV, although In(2R)bwVDe2 has little effect on the position effect variegation of Sb caused by T(2;3)SbV. In(2R)bwVDe2 and C(1;YL)wmMc, and In(2R)bwVDe2 and In(1)wm51b in combination show dominant suppression of variegation of one or both of w and bw, as measured by eye pigment levels. In contrast In(2R)bwVDe2 and T(1;4)wmJ in combination show enhancement of variegation of one or both of w and bw.
Carnitine compounds (L-Carnitine, L-Acetylcarnitine and L-Propionylcarnitine) show a significant suppression on bw variegation. Butyrate gives a weaker suppression.
